A woman walks into her sex therapists office and tells her that her husband is not a very good lover, and they never have sex anymore, and asks what to do about it. The therapist tells her that she has an experimental drug that might do the trick. She tells the woman to give her husband one pill that night and come back in the morning and tell her what happened.
The next day, the woman comes in ecstatic telling the therapist that the pill worked and she and her husband had the best sex ever. She asks her therapist what would happen if she gave her husband two pills and the therapist says she doesnt know, but to go ahead and try it.

The next day, the same thing happens, the woman comes in telling the therapist that the sex was even better than the night before and what would happen if she gave him five pills. The therapist says she doesnt know, but to go ahead and try it.
The next day, the woman comes in limp but happy, and tells the therapist that the sex just keeps getting better and what would happen if she gave her husband the rest of the bottle. The therapist says she doesnt know; its an experimental drug and she doesnt know what a full bottle could do to a person.

Anyway, the woman leaves the therapists office and put the rest of the bottle of pills in the husbands morning coffee.
A week later, a boy walks into the therapists office and says:

"Are you the dumb fuck who gave my mother a bottle of experimental pills?"
"Why, yes, young man, I did.Why?"
